TWEEZERS Filed April 15, 1951 gwmnto a Robfirf E. 5/7103 Patented Nov. 1, 1932 UNITED STATE PATENT OFFICE RQBERT E. SILVIS, F MILL CITY, OREGON Application filed April 15,

erator open the points to release the object held therebetween. Additional tension may be placed upon the jaws by the squeezing of the jaws in the usual manner by the operator.

My invention consists primarily of jaw elements made from spring material terminating in points, or jaws that are normally held together by the inherent spring tension of the material from which the same are made. Arms are associated with each of the jaw members that may be passed around, or through the side walls of the side members to adapt the same for ease of handling by the operator. The arms preferably terminating in enlarged heads to facilitate their manipulation and use.

One of the objects of my invention is to provide a pair of tweezers for use of physicians, dentists, chemists, beauty parlor operators, barbers and in the home. They may be used in the holding, or the maintaining of the article to be held by the tweezers securely within the jaws of the same and which may be released by one hand of the operator and picked up at the will of the operator by simply forcing the arms, associated with the jaw members, together.

A further object of my invention consists in providing a pair, of tweezers that will normally hold an article within the jaws and which may be squeezed by the force of the jaws together in the usual manner by the hand of the operator.

A still further object of my invention consists in forming a pair of tweezers of the minimum number of parts and that will inherently hold an object between the aws and which may be released by the application of pressure to arms associated with the jaws, the pressure being applied in the usual manner.

WVith these and incidental objects in View, the invention consists in certain novel featiues of construction and combination of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which is hereinafter shown withreference to the drawing which accompanies andforms a part of this specification. I

-In the drawing: 1 I I Fig. l is a p'erspective side view of a' pair of tweezers of the type now in common use. Fig. 2 is a sectional end View of the mechanism illustrated in Fig. 1. The same being takenon line 2'2 of Fig. 1, looking in the direction indicated.

Fig. 3 is a fragmentary side view of the mechanism illustrated in Fig. 1 the same being made to illustrate the arms and heads thatare-associated with jaws of the tweezers 7 and illustrating the same disposed at an angle to place the heads of the arms substantially in registry with each other.

Fig. 4 is a perspective side view of a pair of tweezers having offset points, having arms associated with the jaws for spacing the points apart at the will of the operator.

F ig. 5 is a side view of a modified form of a pair of tweezers that are used by chemists and others. The same' not only having, engaging points but having the jaws so formed as to facilitate the holding of test tubes and other articles. Arms being associated with each of the jaws for spacing the jaws apart by the application of pressure to the arms.

Like reference characters refer to like parts throughout the several views.

I form my device of a pair of spaced jaw members 1' and 2. "The jaw members being made of spring material and so tensioned that the engaging points 3 and 4 of the jaws are normally maintained in registry and engaged with each other. The points 5 and 6 may be offset for use of certain tradesmen, andespecially for use by physiciansand den- 'tists: In order that the article held between the points of the offset jaws may be deposited, or placed by the user at substantially right angles of theside walls of'the jaws, arms"? and 8 are associated with the respecg? i T tive jaw members, one end of each arm being secured to one of the jaws and the arm passing through the adjacent jaw member. Heads 9 and 10 are disposed upon the outside end of the respective arms, since there are a pair of jaws and a pair of arms the points of the jaws may be opened double the amount of M 1, that is disposed between the outsi esnrface of the jaw, and the inside surface 12 of the respective heads of the"arms. The arms are placed at such an angle relative to the jaws that the respective heads, terminatin the outer end of the arms are substanti y in alignment with each other, to add greatest comfort and to the user of the same. For use of certain users and particularly ehmmsd other skilled workers the device may bemade as illustrated in Fig. 5.. Wherein the ja-ws 13 and 14 may be made from a single of spring material with the same wound about a common center 15. En-

the outer end of the jaw members. Half circles 18 and 19 being formed within the auterends of the jaws to adapt the same for being used in the clampingv of test tubes and other .reund articles therebetween. Arms 20 and 21ers associated with each of the jaws the arms terminating in loops 22 and 23 that are formed substantially at right angles to the central portion of the arms, to maintain the jaws in registry with each other. The jaws may be made to pass between the parallelly disposed side walls 24 and 25 of the re- .qpectivearm members.

While the term of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated it is a a be understood that a is not intended m confine the invention to the one form of emherein shown and described, as it is susceptible of embodiment in various inl'ms, .all coming within the scope of the claims which follow: V

Whatl claim is: v I I a 1. a device of the clam described, the of a pair of tweezerjaws made single piece of material, a loop discentral of the ends of the jaws, engagmgpoints normally held in registry with each other terminating the ends of the jaws, half circles disposed adjacent each of the Points, an arm associated with each of the aws, said .arms having parallelly disposed side walks between which the other of the Jaws pass, and a loop disposed central of the material from which the respective arms are u made, said loop being disposed substantially at right angles to the body portion of the arm and said loops being substantially in registry aligmnentwith eadl other.

2. a device of the class described, the

of spring material and in one piece, an arm central portion of the g secured to each one of the jaws and formitrg a slot therein, each one of said jaws adap to slide within the slot formed by the arm secured to the other of the jaws thereby adapted to maintain the respective jaws in alignment with each other, a loop disposed upon the free end of the arms, and spring means integrally disposed wifliln} the jaws adapted to normally maintain the pointed ends of said jaws in intimate contact with each other.
